Calculating Production and Material Consumption Rates
Not what you're looking for?
The Ottawa Coat company manufactures winter coats and spring jackets. The winter coat requires 4m of material while the spring jacket requires just 1m. The company wants to minimize the consumption of material. Each winter coat has one zipper while each spring jacket has two. The seamstresses can sew in zippers at a top rate of 5 per hour. Winter coats bring a net profit of $4 and spring jackets a net profit of $3. The company requires that the profit rate be at least $6 per hour. Finally, the material comes in sheets of a certain size, and the company has determined that for maximum efficiency, three times the hourly production of winter coats plus the hourly production of spring jackets, must equal exactly 3. At what hourly rates should the company produce winter coats and spring jackets to minimize the consumption of material? What is the minimum total material consumption rate?

- "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
